This invention relates to gates and operating means therefor, and has for an object the provision of means spaced from the gate upon opposite sides thereof to open or close ,5 thesame, so that the weight of a vehicle may operate to open the gate, and after passage therethrough, to close the gate.

Another object of the invention is the pro vision of depressible means upon opposite sides of the gate to either open or close the gate, depending upon the position of the latter, means being provided whereby should the vdepressible means be wrongfully operated, the opening or closing mechanism will not be affected.

"With the above and other objects in view, the invention includes a pivotally mounted swingable gate which is normally held closed,

with normally raised depressible members spaced upon opposite sides of the gate to releasethe same and open and close the gate through the successful depression of the said depressible members in one direction, means being provided whereby, should either of said members be depressed in the wrong direction with the gate closed, no movement of the gate will occur, while should either of the members be wrongfully depressed with the gate open, it will be moved to its reverse fully open position.

Theinvention further includes other novel features and details of construction, to be hereinafter more fully described, illustrated in the accompanying drawings and pointed out in the appended claim.

In the drawings Figure 1 is a plan view of the invention showing the gate closed and parts removed to more clearly illustrate the mechanism.

Figure 2 is an enlarged section on the line 22 of Figure 1.

Figure 3 is an enlarged fragmentary section on the line 33 of Figure 1.

Figure 4 is a fragmentary view partly in section illustrating the cam and its operating mechanism with the parts in the position 00- cupied when the gate is closed.

Figure 5 is a section on the line 55 of Figure 4. r Figure 6 is a View similar to Figure 4 showing the gate in released position preparatory to opening.

Figure 7 is a longitudinal sectionalview taken substantially on the line 7-7. of Figure 1, the parts being in the position occupied when the gate is closed.

Figure 8 is a like view with the housing omitted and the gatein openposition. I

Figure 9 is an enlarged section taken substantially on the line 99 of Figure 1.

Figure 10 is a fragmentary face view of one of the gate posts and the keeper carried thereby.

Figure 11 is a fragmentary sectional view showing the gate in open position and ele vated so as to prevent its operation by the operating mechanism.

Referring to the drawings in detail wherein like characters of reference denote corresponding parts, the reference character 12 indicates a gate which is mounted between posts 13 and 14. Secured adjacent the post which is rotatableabout the shaft 15 so as to provide a proper bearing.

The gate 12 carries a flanged roller 19 which rides upon the cam edge 17, and the gate also carries an anti-friction bearing 20 which'engages'the shaft 15. An upper anti-friction bearing 21 which is carried by an arm 22 rising from the gate acts, together withthe bearing 20 to insure proper horizontal swing-' ing movement of the gate yet permits the gate tobe moved vertically upon the shaft. The gate carries a housing 23 which extends over and around the cam and this housing is provided with a tapered top 24 to shed water. A post 25 extends from'this housing between the post 13 and the shaft 15 to partially fill the space and prevent passage therethrough. A bracket 26 extends from they post 13 and engages the shaft 15, to stabilize the latter.

The hub 18 of the cylindrical member 15 has rigid therewith a pinion 27. This pinion is engaged by a rack 28 which is carried by a slide bar 29, the latter being'mounted for Cal longitudinal sliding movement in a housing 30. Extending from opposite ends of the slide bar 29 are rods 31, and these rods have secured to their outer ends rightangularly disposed apertured arms 32, through which pass links 33 and 34, the latter being relatively short. These links carry stops 35 and 36 respectively which are adapted to engage the arms 32, while the ends of the links opposite the stops are pivotally secured as shown at 38 to oppositely extending arms 39 which are fast with a rock shaft 40.

The rock shaft 40 is mounted in suitable bearings 41 which extend transversely of the roadway and carry upwardly extending lugs 42 which provide gate operating members. The lugs or gate operating members are normally held in raised position by means of weights 43 which are carried by the arms 39.

By reference to Figure 7 of the drawings it will be seen that movement of the rock shaft in one direction will cause the stop 35 of the link 33 to engage the arm 32, while movement of the rock shaft in an opposite direction will cause the stop 36 of the link 34 to engage this arm32. Due to the difference in the length of the links however less movement of the rock shaft is required to engage the stop .36 than is required to engage the stop 35. The purpose of this difference in movement will be hereinafter explained.

The gate 12 carries a latch bar 44 which extends beyond the free end of the gate and is adapted to engage a keeper 45 which is adjustably secured to the gate post 14 as shown at 46. This keeper is provided with spaced notches defining stop shoulders 47 and 48 upon opposite sides of the center of the keeper so that as the gate is moved to a closed position the latch bar 44 will ride upon one of the inclined surfaces 49 of the keeper and will engage the shoulder 47 to limit move ment in this direction. The keeper will then drop into the notch and the shoulder 48 will prevent reverse or opening movement of the ate.

b Assuming the gate to be closed and the vehicle is travelling in the direction of the arrow shown in Figure 8, depression of the operating member 42 at the left of the said figure will rock the shaft 40 so as to swing the arms 39 to the position shown by the dotted lines in Figure 3. During this movement, the stop 36 of the link 34 will engage the arm 32 so as to move the parts so as to cause the slide bar 29 to be moved to the left of the said figure. This movement will cause the cam 17 to rotate substantially a quarter turn, moving the cam from the position shown in Figure 4 to the position shown in Figure 6. This movement of the cam will cause the gate to ride upward along the in clined edge of the cam, whereupon the latch will be released from the keeper. As soon as the latch is released from the keeper, the

weight of the gate will cause the roller to travel down to the low portion of the cam, and as the cam has been given a quarter turn, the gate will be swung ninety degrees so as to engage a keeper 50 carried by a post 51. One of these posts is provided upon opposite sides of the gate.

The vehicle may then pass through the gate and depress the operating member 42 in the direction of travel of the vehicle. As the stop 35 of the link 33 is substantially in contact with the arm 32 at this end of the gate, due to the movement of the slide bar and the arm 32, depression of the member 42 just mentioned, will cause the stop 35 to engage the arm 32 and operate the cam 17 in a reverse direction so that the roller 19, which now occupies the lowermost position upon the cam, will be raised. The roller will then occupy a position upon the cam opposite that shown in Figure 6, the cam being returned to toe position occupied when the gate is closed. Weight of the gate will cause the roller to seek the low part of the cam so that the gate will return to its normal position.

Should either of the gate operating members 42 be depressed in the wrong direction, no movement of the slide will occur and consequently no movement of the gate. This is due to the increased length of the link 33 which are sufficiently lon to permit the operating members to be depressed outwardly without exerting a pull on the slidebar. This may be seen from Figure '7 of the drawings wherein the parts are in the position occupied when the gate is closed. Outward pivotal movement of either of the arms 39 will be permitted without moving the slide due to the spacing of the stops 35 from the arms 32; However, inward pivotal movement of the arms 39 will cause the stops 36 to engage the arms 32 and operate the gate to an open position as previously described. The weights 43 act to maintain the arms 39 and consequently the operating members 42 in raised position. In the event the gate 1s open as shown in Figure 8 of the drawings. depression of the operating member 42 at the right end of Figure 8, in. an inward direction will swing the gate from the open position shown to the opposite open position. This is due to the cam making a one-half revolution so that the roller will ride up and. over the high part of the cam. Increased movement of the cam is due to the fact that the arm 39 at the right of Figu e 8 is disposed at substantially forty-five degrees and movement of the member 42 inward this end of the figure will provide for an increased movement of the slide bar and consequently increased movement of the cam.

Pivotally mounted upon each of the posts 51 as shown at is latch 54. This latch is normally disposed in a vertical direction, but may be held horizontal by means of a stop 55 and by manually raising the gate 12 so that its lower edge rests upon this latch 54:, the roller 19 will be spaced above the cam, so that rotation of the latter will not afiect movement of the gate. a

The invention is susceptible of various changes in its form, proportions and minor details of construction and the right is herein reserved to make such changes as properly fall within the scope of the appended claim.

Having described the invention what is claimed is A hinge structure comprising a vertically supported shaft, a cylindrical member having a cam edge surrounding the shaft'a closure member slidable over said cylindrical member and journaled upon the axis of the shaft and adapted to be raised and lowered when turned, brackets adapted to be mounted upon a post to support the shaft in vertical position, a bearing housed within the closure member and slidable upon the lower portion of the shaft and a vertical arm attached to the closure member and having at its upper end an angularly disposed hinge portion slidable upon the upper portion of the shaft.

In testimony whereof I affix my signature.
